  • Publication number: 20100265263
    Abstract: An image display method including following steps is provided. A backlight of a display panel is adaptively adjusted according to a backlight adjustment factor related to the intensity value of an external light and the brightness of an original image. Brightness factors of the original image are corrected according to the adjustment of the backlight, and the original image is reset by using the corrected brightness factors and original color factors. Thereby, the problem of image distortion caused by backlight adjustment can be reduced.

  • Publication number: 20050217300
    Abstract: A cooling system includes a cooling fan, a fan input-output module for transmitting a control signal to the fan for controlling the rotational speed of the fan, and a chipset interface for generating the fan control signal based on a change in a vital temperature of the computer system. Further provided is a controller for receiving the vital temperature and forwarding the vital temperature to the chipset interface, and a temperature transducer for generating the vital temperature and outputting the vital temperature to the controller. The chipset interface monitors a rotational speed of the cooling fan, and monitors a vital temperature of the computer system. The chipset interface then sets the fan power based on a change in the vital temperature. When the vital temperature decreases, the fan power is reduced to slow the fan, and when the vital temperature increases, the fan power is increased to speed the fan.
